99% of global ice is located in Antarctica and Greenland. If they both melted entirely sea level would rise 200’. The ice shelves make up one-half percent of global ice, if they melted entirely sea level would rise 14 inches. Sea ice comprises 6% of global ice, they average 6 feet in thickness, if they melted entirely sea level would rise four inches. If the 200,000 temperate zone global glaciers melted entirely, sea level would rise two feet. Antarctic ice is as much as three miles thick, Greenland one mile. For Antarctic ice to melt, temperatures must rise at least 54 degrees F.﻿

Multidecadal Oscillations in the Pacific and the Atlantic are acknowledged to be the result of natural processes. The warm mode of the Pacific results in warm water off Alaska that can enter the arctic through the Bering Strait and produce arctic ice melt. The warm mode of the AMO also results in warming in the North Atlantic waters, which are carried by the North Atlantic current into the arctic reducing ice depth and extent. When you combine the two cycles, you can explain the temperature and ice cover variances of the past 110 years for the Arctic.﻿
